Well, 70kms out coming from LPCS they were most likely overhead the Priorat, which is a hilly wine-growing area to the west of Reus. If they had a tech issue, nowhere really to set down, no matter the wx. Sad, RIP.

D-ETFT, a Mooney M20K.
Weather was IMC in the area, flight was on a VFR fpl. The pilot contacted ATC and told them they were having problems, and were unable to reach LERS. Finally he reported loss of engine, according to local ATC.
